You have to work out what their current centers are, say the instance center is 10,10,10 then then add a static transform to move these to the origin, -10,-10,-10, then if to want to move these instances around you could simply flatten the object so the transform is applied to the verts etc or add a dynamic transform above the static transfom among other options

Hi all, just a simple question, and I can't find related topics on the group. How can I get/set my components' local center coordinate? I have lots of components, all of them are contained in one 3DS model and have it's own local coordinate. I used matrixtransform to set a component's position to (0,0,0) but it didn't translate to the origin, and all components' position is like in the model. Then I used matrixTransform to rotate a component around it's local axis, it still worked but it's position (gettrans()) always change. I really don't understand this, I don't want to seperate the model to many components. Any support'd be appreciated. Thanks, Best Regards. -- ЯicKy
